19 Claims. ,(Cl. 114-210) This invention relates to marine equipment and more particularly, to apparatus for weighinganchors or grapnels, especially those used with small boats and other vessels, the primary object being to eliminate the somewhat difiicult problem incident to hoisting of anchors especially by those not accustomed to, nor particularly skilled in such operation.

Present day users of small boats and larger vessels primarily as a means of recreation and usually during vacation periods, not normally being particularly proficient in the handling of such craft, are confronted with a burdensome task whenever it is desired to anchor the vessel and thereupon raise the anchor when it is again desired to get under way. The larger class of sports equipment especially is equipped with relatively heavy anchors as a matter of necessity and even after the novice handling the vessel is able to pull the anchor loose from its ground-penetrating condition, the weight of the anchor, together with the chain attached thereto, is such that quite frequently no attempt is made to drop anchor because of the problem that is thereafter presented.

Accordingly,'it is the most important object of the present invention to provide positively operating, troublefree apparatus for hoisting anchors, all of which is relatively inexpensive, not particularly difiicult to install, and which requires virtually no skill whatsoever on the part of the user to place the same into operation.

Incident to the provision of suitable apparatus capable of performing the above-mentioned functions is the problem of proper positioning of the anchor with respect to the vessel at the side thereof when the anchor is hove up and secured or made fast. The shape or configurations of the side of the vessel and the anchor are such that, in order to secure the anchor in place at the side of the vessel without necessity of hauling the anchor on board and without undue protuberance of the anchor beyond the side of the vessel, it is necessary that proper movement be imparted to the anchor during hoisting thereof so as to attain the proper positioning.

It is another important object of the present invention, therefore, to provide in hoisting apparatus, novel structure for not only permitting extension of the shank of the anchor into the vessel itself, but causing the anchor to turn or rotate to a position where the flukes thereof extend upwardly and nest close to the side of the vessel whereby the fiukes and arms only of the anchor are exposed exteriorly of the craft when the anchor is in the fully hoisted position.

It can be appreciated also that another problem incident to effecting the advantageous results above set forth, has to do with the fact that the anchor is freely suspended from the anchor chain; consequently, as it approaches the side of the boat, there would normallybe no assurance of proper alignment except for the provision of means permitting the anchor to swing into position prior to final hoisting operations which pull the shank into the side of the boat.

It is, therefore, an extremely important object of the present invention to incorporate in the anchor hoist of the instant invention, means to at least momentarily interrupt the operation ofv the mechanism to permit proper aligning of the anchor with a saddle on an inner hawse pipe that is in turn reciprocably and rotatably carried by the vessel.

' Other objects include the provision of novel structure for not only causing rotation of the inner hawse pipe as the same is reciprocated, but means to yieldably bias the latter to a position extending outwardly beyond the vessel when the anchor is cast loose; and the provision of means for interrupting the operation of the mechanism as just above mentioned taking the form of a suction cup which holds an electric switch in an open condition for a predetermined period of time.

A single and preferred embodiment of the instant invention is illustrated in the drawings, wherein: V

Fig. 8 is a wiring diagram illustratingthe electrical components of the anchor hoist.

It is, of course, preferred that anchor 10 be attached to vessel 12 at one side 14 thereof, adjacent its bow 16. Accordingly, a hawsehole (not shown) is provided in the side 14 of the vessel 12 adapted to receive an elongated, outer hawse pipe 18 that extends inwardly and upwardly at an angle, the entire pipe 18 being housed within the vessel 12 and being mounted in place by inner and outer plates or facings 20 and 22 respectively.

When the anchor 10 is'secured in the position illustrated in Figs. 2 and 4, an inner hawse pipe 24 is fully telesco-ped within the pipe 18 as seen in Fig. 3 and saddle means 26 on the outermost end of the pipe 24 is housed or nested within a correspondingly shaped cavity 28 in the outer plate or head 22.

It is apparent by examination of Figs. 1 and 2 that pipe 24 is reciprocable within the pipe 18 longitudinally thereof, to the position shown in Fig. 1 extending outwardly and downwardly beyond the side 14 of the vessel 12 when anchor 10 is cast loose. However, thepipe 24 is also rotatable relative to pipe 18 and is caused to rotate by virtue of an interconnection between the two pipes 18 and 24. Such interconnection includes a spiral slot 30 in the pipe 18 extending longitudinally thereof which slidably receives an outwardly-extending radial pin 32 rigid to the pipe 24, it being seen that the .extent of outward movement of the pipe 24 is limited :as .the

Patented May 24, 1960 pin 32 abuts the lowermost end of the slot 30 adjacent the point of connection between pipe 18 and the plate 20.

While movement of the pipe 24 inwardly into the pipe 18 is caused, as will hereinafter be made clear, by the force of the anchor engaging the saddle 26, pipe 24 is yieldably biased outwardly to the position shown in Fig. 1. This is accomplished through the medium :of a spring-loaded shaft 34 rotatably carried by a U-shaped bracket 36 that is in turn carried by the pipe 18 or more particularly, by tubular boss 33 forming a part of the inner plate 20 and which receives the pipe .18. A windlass 40 includes a drum or grooved pulley 42 about U which is wound a cable 44 when the pipe 24is extended outwardly. One end of the cable '44 is secured rigidly to the drum 42 and the opposite end of cable 44'is attached to the pin 32.

Drum 42 is attached to the shaft 34 for rotation therewith and a spring 46 coiled about the shaft 34 has one end 48 thereof attached to the drum 42. The opposite end of the spring 46 is similarly secured to a springtensioning set collar 50 releasably attached to the shaft 34. Spring 46 is always under tension even when pipe 24 is extended as shown in Fig. 1, at which time the cable 44 is wound on the drum 42 as aforementioned. Manifestly, such tension on spring 46 is increased when cable 44 is unwound as shown in Fig. 3, and the anchor 10 secured.

Hoisting mechanism broadly designated by the numeral 52, is mounted on the innermost and uppermost end of the pipe 18 and may be braced or secured to the vessel 12 in any other manner if desired. It includes a U- shaped bracket 54 having a head 56 receiving the pipe 18. Reduction gearing broadly designated by the numeral 58 carried by the bracket 54, in turn supports a prime mover such as an electric motor 60. Output shaft 62 of gearing 58 rotatably carried by bracket 54 is operably connected with a pulley 70 by a slip clutch 66 whose spring 68 is coiled about the shaft 62, pulley 70 being free on shaft 62 and receiving a chain 72. Manifestly, clutch part 64 is keyed to shaft 62 for rotation therewith and reciprocation against the action of spring 68, and clutch part 65 is fixed to or made a part of pulley 70.

Anchor chain 72 has one end thereof attached to one end of shank 74 forming a part of the anchor 10. The loose end of the chain 72 may hang freely within the boat 12. It is thus seen that when the anchor 10 is cast loose, chain 72 extends from shank 74, through the pipe 24, upwardly and inwardly through the pipe 18 and over the pulley 70 to thereupon hang vertically within the boat 12 from the pulley 70.

It is apparent from Fig. 8 of the drawings that the reversible motor 60 may be driven from a suitable source of electrical energy such as a battery 76. Manual switches 78 and 80 ganged together for movement simultaneously, are illustrated in Fig. 8 in the neutral position with motor 60 de-energized. Manifestly, when the switches 7880 are swung in one direction, the motor 60 rotates clockwise and when switches 78-80 are swung in the opposite direction, the motor 60 rotates anticlockwise.

A switch 82 shown also in Fig. 5, is interposed in the circuit for motor 60 which energizes the latter in a direction to hoist or raise the anchor 10. Switch 82 is normally open as shown in Fig. 8 when the anchor 10 is secured.

Switch 82 is mounted within a box 84 that is adjustably carried by one upstanding leg 86 of the bracket 54 through the medium of a strap 88 swingable about the axis of shaft 62 and attached rigidly to the box 84. The leg 86 is provided with an arcuate slot 90 concentric with the shaft 62 and bolt and wing nut means 92 for attaching the strap 88 to the leg 86, rides freely in the slot 92 when adjustment is desired.

Box 84 .is provided with a bottom .94 that is vertically ngable by virtue of a pivot pin 96 and limited in its downward movement by a stop pin 98. Ann 100 forming a part of the switch 82, the latter of which is mounted in the box 84, is disposed within the path of swinging movement of the bottom 94 upwardly away from the pin 98. An upstanding pin 102 on the bottom 94 within box 84, supports a suction cup 104 adapted to engage and attach to the lowermost face of top wall 106 of box 84 when the bottom 94 is raised. A scratch or groove 108 formed in the lower face of wall 106, vents the cup 104 to the atmosphere for breaking the vacuum after a predetermined period of time to cause the cup 104 to release lits hold on the wall 106.

The chain 72 is provided with spaced-apart protuberances 110 and 112 on two of its links, both of which are substantially close to the shank 74 of anchor 10, and each of which is adapted to engage a boss 114 on the lower face of the swingable plate or bottom 94 of box 84.

The anchor -10 chosen for illustration, includes as a part thereof, in addition to the elongated shank 74, a crosshead 116 at that end of shank 74 opposite to chain 72 provided with oppositely-extending arms 118 and 120 which are in turn provided with conventional groundpenetrating flukes 122. The saddle 26 is especially formed so as to be lockable with the crosshead 116 and is, therefore, provided with opposed, outwardly flared lips 124 and 126 which partially embrace and, therefore, interlock with the crosshead 116 as seen in Figs. 2 and 4 as soon as the crosshead 116 comes into engagement with the saddle 26 to the end that the anchor 10 and the pipe 24 rotate and move inwardly relative to pipe 18 as a unit during the final stage of the hoisting operation.

Assuming anchor 10 to be secure as shown in Figs. 2, 3 and 4, movement of the switches 78 and 80 in one direction, closes circuit 128 through motor 60 to energize the latter and drive the shaft 62 in one direction through gearing 58. This places the hoisting tackle, broadly designated by the numeral 130 (including pulley 70 and chain 72) into operation to pay out the chain 72 and thereby permit the anchor 10 to descend under influence of its own weight. As soon as the pressure of crosshead 116 on saddle 26 is relieved, the power means, including spring 46, operates to project the pipe 24 outwardly to the position shown in Fig. 1.

Manifestly, the tension in spring 46 rotates the shaft '34 and, therefore, the drum 42 to exert a pull on the cable 44, winding the latter on the drum 42. Cable 44 pulls upon the pin 32 and as the latter rides along the slot 30, pipe 24 not only moves outwardly, but rotates. Accordingly, pipe 24 is held to the outer end of its path of travel throughout the time the vessel is at anchor. A stop (not shown) may be provided on the inner end of chain 72 to limit the extent to which the same may be payed out and as soon as clutch 66 commences slipping, the noise thereof will alert the operator of the boat 12 to return the switches 78 and 80 to the neutral position shown in Fig. 8.

The anchor-weighing apparatus is placed into operation to hoist the anchor 10 by closing circuit 132 and at that time switch 82 is closed. As the shank 74 of anchor 10 approaches the saddle 26 and before the same enters into the pipe 24, the protuberance 112 on chain 72 engages boss 114 to raise the plate 94 oi? the stop 98. As the plate 94 engages switch arm 100, the switch 82 is opened to the position shown in Fig. 8, thereby de-energizing the circuit 132 and, therefore, the motor 60 to interrupt the operation of the hoisting tackle .130 in its anchor-hauling function.

Upward movement of the plate 94 also forces the suction cup 104 against the wall 106, thereby holding the switch 82 open for a predetermined period of time notwithstanding the fact that protuberance 112 will have moved out of engagementwith the boss 114 by the time the motor 60 actually comes to a stop.

,It is evident thatthe lengthof time.switch-82 remains open, depends upon how long the suction cup 104 maind tains its hold on the wall 106 and this time element may be varied by the extent to which air is permitted to bleed into the cup 104, through the opening 108'. It has been' found that cups 104 made from proper material will not readily release and it is for this reason that the scratch or mark 108 is provided in the wall 106.

Since the shank 74 is freely suspended from the chain 72 and the anchor is capable of swinging and spinning as it is being elevated, the interval of time during which the motor 60 remains de-energized should be sufliciently long to cause the anchor 10 to come to rest substantially and align itself properly with the pipe 24 so that the crosshead 116 will ultimately move properly into the saddle 26.

After the cup 104 releases and the plate 94 returns to its position resting on stop 98, switch 82 automatically closes, re-energizing the circuit 132 and, therefore, prime mover 60. Shank 74 enters the pipe 24 and inasmuch as the shank 74 is initially vertical, an elongated opening 134 is provided in the pipe 24 to clear the shank 74. Noteworthy is the factthat the opening 134 is disposed upwardly when the pipe 24 is extended outwardly.

The inward slope of the side 14 of boat 12 is suflicient to clear the inwardly-facing fiukes 122 and the shank 74 enters the pipe 24 and as soon as the crosshead 116 moves into nested engagement with the saddle 26, the hoisting tackle 130 will force the pipe 24 inwardly against the action of spring 46, thereby unwinding the cable 44 and increasing the tension on spring 46.

Since pin 32 rides in slot 30 during inward movement of the pipe 24, the latter, together with the anchor 10, rotates as a unit until the same is fully secured, thereby swinging the fiukes 122 to the position shown in Figs. 2 and 4 extending upwardly and'outwardly from the crosshead 116 in substantial parallelism with the inclined side 14 of boat 12. By the time the saddle 26 comes to rest fitted within the cavity 28, the second protuberance 110 will have engaged the boss 114 again opening the switch means 82 and de-energizing the motor 60. The fact that switch 82 remains open for a short perio'd of time during the succeeding anchor-weighing operation is of no consequence since switches 78 and 80 are then in their anchor-lowering position, and the switch 82 is not in series with the energizing circuit 128-132 for motor 60.

If desired, a U-shaped guide 136 for the chain 72 to maintain the same on the pulley 70, may be held in place through the medium of a suitable mount 138 on the bracket 54.
